SCH 4U Chapter 7 Chemical Systems in Equilibrium Equilibrium Calculation Exercise 3 Nelson: Section 7.2, 7.51.If Keqfor the production of NH3 (g)is 2.37 x 10-3L2∙mol-2and [N2 (g)] = 2.0 mol/L, [H2 (g)] = 3.0 mol/L, calculate [NH3 (g)]. (0.36mol/L) 2.A reaction vessel with a capacity of 1.0 litre in which the reaction SO2 (g)+ NO2 (g)↔SO3 (g)+ NO(g)had reached a state of equilibrium, was found to contain 0.8 mole of SO3 (g), 0.4 mole of NO(g), and 0.2 mole of NO2 (g)and 0.4 mole of SO2 (g). Calculate the equilibrium constant for the reaction. (4.0) 3.Calculate the Keq for the reaction 2NO(g)+ O2 (g)↔2NO2 (g)if it is known that at equilibrium in a container of 0.76 litres, there are 0.19 moles of NO2 (g), 2.65 x 10-4moles of NO(g)and 0.606 moles of O2 (g). (6.4 x 105L/mol) 4.The Keqfor the following reaction is 3 at 1000°C. 2SO2(g)+ O2(g)↔2SO3(g). An equilibrium system at 1000°C contains 18 moles of SO3(g)and 6 moles of SO2(g)in a 3 litre vessel. How many moles of O2(g)are present in the equilibrium system? (3 mol) 5.Given the following reaction: PCl5 (g)
